Abstract

A connecting device, in particular for installing at least one opening stay on a window leaf has a rail, which can be guided as far as possible in the direction of the first longitudinal axis thereof into a groove of the connecting device. The groove engages at least in sections behind the rail. The blocking of the longitudinal displaceability of the rail in the groove is guaranteed at least counter to the first longitudinal direction by a projection connected to the rail, which projection engages in a recess in the region of the groove. The projection is held in the installed position of the connecting device by a spring element in the recess. A spring element is arranged on the rail preferably in a limited movable manner. Alternatively or in addition, the connecting device can comprise a cap which holds the projection in the installed position of the connecting device indirectly and/or directly at least partially in the recess.

DETAILED DESCRIPTION OF THE INVENTION

(8) FIG. 1 shows a window 10 comprising a sash 12 which comprises a sash frame 13, and a window frame 14. The sash 12 is connected to the window frame 14 by means of at least one stay (not shown), in particular two stays. In this case, the stays are arranged on the sash 12 by means of a connecting device 16.

(9) FIG. 2 shows part of the connecting device 16. The connecting device 16 comprises a rail 18, a groove 20 and a cap 22. The inner contour of the groove 20 has a C-shaped cross section. The rail 18 can be introduced into the groove 20 in a first longitudinal direction 24. If the rail 18 is inserted in the groove 20 as far as a second stop 42 (see also FIG. 3a), a projection 26 (see also FIG. 3b), which points downwards in FIG. 2 and which is not immediately visible in FIG. 2, locks in a recess 28 in the groove 20. The projection 26 being locked in the recess 28 prevents the rail 18 from being pulled out counter to the first longitudinal direction 24. Furthermore, a first stop 30 is formed by the recess 28, which stop prevents the rail 18 from being inserted further in the first longitudinal direction 24. The first stop 30 and the second stop 42 together form a stop which prevents the rail 18 from being inserted further in the first longitudinal direction 24 when the connecting device 16 is assembled.

(10) In the context of the present invention, the rail 18 is referred to as being inserted in the groove 20 when the rail 18 is inserted for the most part into the groove 20 such that it reaches its end position. In this state, the projection 26 can protrude into the recess 28 at least in part.

(11) The groove 20 is part of a profile 32, in particular in the form of an extruded profile. The profile 32 is screwed onto the sash frame 13 (see FIG. 1). The rail 18 that is inserted in the groove 20 is therefore securely and rigidly connected to the sash 12 (see FIG. 1).

(12) FIG. 3a shows the connecting device 16 when partially assembled. It can be seen from FIG. 3a that the connecting device 16 comprises a spring element 34. The spring element 34 is in the form of a leaf spring. The spring element 34 is connected to the rail 18 by means of rivets 36, 38. According to FIG. 3a, one end of the rail 34 is bent away from the rail 18. When the spring element 34 is unactuated, the longitudinal axis of the spring element 34 extends in parallel with the longitudinal axis of the rail 18.

(13) In order to assemble the connecting device 16, the spring element 34 is bent, in part, away from the rail 18 in order to prevent the projection 26 (see also FIG. 3b) from pressing against an end face 40 of the groove 20.

(14) The second stop 42 indicates to an installer that the rail 18 is inserted in the groove 20 such that it is in its end position. The second stop 42 is formed on a first arm 44 and a second arm 46.

(15) Furthermore, the arms 44, 46 engage part of the rail 18 from behind in order to prevent the spring element 34 from bending too far perpendicularly to the bottom of the groove 20. More precisely, a third stop 47 prevents the spring element 34 from bending too far, which stop is formed by the arms 44, 46. At least the first arm 44, in particular the two arms 44, 46, is/are, as shown in FIG. 3a, formed integrally with the spring element 34, and therefore the connecting device 16 can be produced in a particularly simple manner and has a structurally simple design.

(16) FIG. 3b is a longitudinal section through the connecting device 16 according to FIG. 3a. The projection 26 arranged on the spring element 34 can be seen particularly clearly in FIG. 3b.

(17) The projection 26 is in the form of a pin. The projection 26 is fastened to the spring element 34 by means of rivets. The projection 26 comprises a notch 48 by means of which the projection 26 can be held in the recess 28, as explained in the following.

(18) FIG. 4a shows the connecting device 16 when completely assembled. In this state, when the rail 18 is arranged in the groove 20, the cap 22 can be pushed onto the profile 32 to such an extent that the inside of the cap 22 presses against the end face 40 of the groove 20 or the profile 32. The cap 22 can be mounted such that it reaches its end position only if the projection 26 (see FIG. 4b) is in its end position in the recess 28 (see FIGS. 3b and 4b).

(19) FIG. 4b is a longitudinal section through the connecting device 16 in the end position in which it is completely assembled. It can be seen from FIG. 4b that the cap 22 comprises a fork 50 which surrounds the notch 48 (see also FIG. 3b) of the projection 26 at least in portions. In the present case, the cap 22 presses the spring element 34 against the rail 18 and the fork 50 of the cap 22 holds the projection 26 in the recess 28 such that it cannot move. The connecting device 16 according to the invention is thus particularly compact, can be opened in a reliable manner, and yet can be assembled without using any tools.

(20) FIG. 4c is an enlarged partial view of the connecting device 16 according to FIG. 4b which shows how the projection 26 is secured by means of the fork 50. The fork 50 is injection moulded at least in part in the cap 22 or is locked at least in part in the cap 22 with an interlocking fit, and therefore the fork 50 is captively arranged in the cap 22.

(21) If all of the figures of the drawings are considered in combination, the invention relates to a connecting device 16, in particular for mounting at least one stay on a window sash 12. The connecting device 16 comprises a rail 18 which can be introduced as far as possible into a groove 20 in the connecting device 16 in the direction of the first longitudinal axis 24 of said rail. The groove 20 engages the rail 18 from behind at least in portions. A projection 26 that is connected to the rail 18 and engages in a recess 28 in the region of the groove 20 ensures that the longitudinal movement of the rail 18 in the groove 20 is blocked at least counter to the first longitudinal direction 24. The projection 26 is held in the recess 28 by a spring element 34 when the connecting device 16 is in the assembled position. The spring element 34 is preferably arranged on the rail 20 such that it can move in a limited manner. Alternatively or additionally, the connecting device 16 can comprise a cap 22 which indirectly and/or directly holds the projection 26 in the recess 28 at least in part when the connecting device 16 is in the assembled position.
